A, B, C, D, and E are the five members in a family. Among them, there is one married couple. E is unmarried and is the brother of A, D is the sister of E, C is the only married female and the mother of D. B and E are only males in the group. Who is the father of A?

Solution

✅ Correct Option: 4

The only males are B and E, and E is unmarried, so the married man must be B. C is the only married female, so B and C form the couple.

C is the mother of D, and D, E and A are siblings, so C is mother to all three. Therefore B is their father, including the father of A.
